Description

A deburring and chamfering device Technical Field

[0001] This application relates to the field of machining tools, and more specifically, to a deburring and chamfering device. Background Technology

[0002] During machining or assembly, burrs often form on the end face edges of studs due to cutting, making nut assembly difficult. Therefore, it is usually necessary to chamfer the end face edges of the studs before assembly to remove these burrs. Chamfering also facilitates nut assembly later. Current machining methods typically involve manually scraping away burrs and chamfering the stud edges with a cutting tool, which is not only time-consuming and labor-intensive, but also makes it difficult to ensure consistent machining, often resulting in uneven chamfering. This leads to difficulties in nut assembly, or even situations where the nut cannot be assembled at all, affecting machining efficiency and yield. Summary of the Invention

[0003] The technical problem to be solved by the embodiments of this application is the low efficiency of manual chamfering.

[0004] To address the aforementioned technical problems, this application provides a deburring and chamfering device, which employs the following technical solution:

[0005] A deburring and chamfering device includes: a handle, a blade, and a pressure block; one end of the handle is provided with an operating lever, and the other end is provided with a mounting surface; the blade is disposed on the mounting surface, and the pressure block abuts against the side of the blade away from the mounting surface;

[0006] One end of the blade is provided with a cutting edge, and the cutting edge is symmetrical about the center line of the blade.

[0007] Furthermore, a first chip removal groove is provided on the mounting surface, the first chip removal groove extending to the end face of the tool holder, and a second chip removal groove is provided on the end face of the pressure block near the blade, the second chip removal groove extending to the end face of the pressure block.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] As shown in Figures 1-5, a deburring and chamfering device includes a handle 1 and a pressure block 2. One end of the handle 1 is provided with an operating lever 11, and the other end with a mounting surface 12. The operating lever 11 facilitates operation of the deburring and chamfering device for deburring and chamfering operations. For example, the operating lever 11 can be mounted on automated equipment (such as a drilling machine), and the automated equipment drives the handle 1 to perform the operation. A blade 3 is provided on the mounting surface 12. The pressure block 2 abuts against the side of the blade 3 away from the mounting surface 12, thereby clamping the blade 3 through the handle 1 and the pressure block 2, preventing the blade 3 from shifting during processing. The pressure block 2 and the blade 3 are detachably connected to the handle 1. This detachable connection facilitates the replacement or maintenance of the blade 3, extending the service life of the deburring and chamfering device.

[0030] As shown in Figure 4, one end of the blade 3 is provided with a cutting edge 31, which is symmetrically arranged along the center line of the blade 3. The thickness of the blade 3 does not exceed 3 mm, the cutting edge of the cutting edge 31 is V-shaped, and the thickness of the end of the cutting edge 31 does not exceed 0.2 mm. The V-shaped cutting edge allows the deburring and chamfering device to perform chamfering in both forward and reverse rotation, improving its practicality. During processing, the cutting edge 31 is brought into contact with the workpiece, and the V-shaped cutting edge scrapes away the burrs on the edge of the workpiece end face, achieving the function of chamfering the workpiece end face. By setting the cutting edge 31 symmetrically along the center line of the blade 3, it is possible to quickly align it with the axis of the workpiece during processing, thereby improving processing efficiency and ensuring processing accuracy, resulting in a uniform chamfer on the workpiece end face.

[0031] As shown in Figures 3 and 5, a first chip removal groove 13 is provided on the mounting surface 12, extending to the end face of the tool holder 1. A second chip removal groove 21 is provided on the end face of the pressure block 2 near the blade 3, extending to the end face of the pressure block 2. By setting the first chip removal groove 13 and the second chip removal groove 21, the chips generated during the chamfering process can be smoothly discharged, avoiding the impact of chips on machining accuracy, and improving machining efficiency and precision.

[0032] In this embodiment, both the first chip removal groove 13 and the second chip removal groove 21 are conical structures. The conical structure of the chip removal groove allows for the smooth discharge of machining chips, while also ensuring that the mounting surface 12 and the pressure block 2 have a sufficiently large contact area with the cutting tool 3. This allows the cutting tool 3 to be clamped and fixed by the tool holder 1 and the pressure block 2, reducing the possibility of displacement of the cutting tool 3 during machining. In other embodiments, the first chip removal groove 13 and the second chip removal groove 21 can also be other structural forms, such as spiral grooves, spherical grooves, etc.

[0033] During the actual processing, the operating lever 11 on the tool holder 1 can be manually held or the operating lever 11 can be installed on the drive device of the automated equipment. Then, the end face of the workpiece to be processed is pressed against the cutting edge 31, so that the axis of the cutting edge 31 coincides with the axis of the workpiece. Then, by driving the tool holder 1 to rotate, the blade 3 is driven to rotate together. The cutting edge 31 on the blade 3 comes into contact with the end face of the workpiece, thereby scraping off the burrs on the edge of the end face of the workpiece, achieving the purpose of chamfering the end face of the workpiece. The chips generated by chamfering will splash into the first chip removal groove 13 and the second chip removal groove 21, and are discharged from the end face of the first chip removal groove 13 and the second chip removal groove 21 under their own gravity or mutual compression.

[0034] Because the cutting edge 31 has a symmetrical structure, this deburring and chamfering device only requires the tool holder 1 to rotate 180° to chamfer the entire end face of the workpiece during operation. In actual operation, to ensure a smooth and flat chamfered surface, the tool holder 1 is usually driven to rotate more than 180° but less than 360°. In other words, this deburring and chamfering device does not need to drive the blade 3 to rotate 360° to complete the chamfering of the entire end face of the workpiece, thus improving processing efficiency.

[0035] In this embodiment, the blade 31 is V-shaped; in other embodiments, the blade 31 can also be other symmetrical shapes, such as C-shaped, arc-shaped, etc.

[0036] As shown in Figure 3, for ease of assembly, a limiting step surface 14 is provided on the tool holder 1. The limiting step surface 14 is connected to the mounting surface 12, and one end of the blade 3 and one end of the pressure block 2 are respectively connected to the limiting step surface 14. During assembly, the blade 3 is first placed on the mounting surface 12, so that one end of the blade 3 is connected to the limiting step surface 14; then the pressure block 2 is placed on the blade 3, so that one end of the pressure block 2 is also connected to the limiting step surface 14; then the tool holder 1, blade 3, and pressure block 2 are connected and fixed. The limiting step surface 14 can be used to position the blade 3 and pressure block 2, thereby improving assembly efficiency.

[0037] In this embodiment, an internal threaded hole 15 is provided on the mounting surface 12, a limiting hole 22 is provided on the pressure block 2 at a corresponding position to the internal threaded hole 15, and a connecting through hole 32 is provided on the blade 3 at a corresponding position to the internal threaded hole 15. A connecting screw 4 is provided in the limiting hole 22, and the connecting screw 4 passes through the connecting through hole 32 and is threadedly connected to the internal threaded hole 15. During assembly, after the blade 3 and pressure block 2 are placed, the connecting screw 4 is passed through the limiting hole 22 and the connecting through hole 32 in sequence, then the connecting screw 4 is inserted into the internal threaded hole 15, and finally the connecting screw 4 is tightened to the internal threaded hole 15. In this way, the handle 1, blade 3 and pressure block 2 can be connected and fixed. When the blade 3 needs to be replaced or maintained, the connecting screw 4 can be removed to separate the blade 3 from the handle 1. In other embodiments, the handle 1, blade 3 and pressure block 2 can also adopt other detachable connection methods; for example, snap-fit, etc.

[0038] In one embodiment, the limiting hole 22 can be a stepped hole. The limiting hole 22 in the form of a stepped hole can accommodate the head of the connecting screw 4, thereby making the surface of the entire deburring and chamfering device relatively flat, improving the aesthetics, and also making it easy to store.

[0039] To simplify the assembly process, in this embodiment, the operating lever 11 and the tool holder 1 are integrally formed, thus eliminating the need to assemble the operating lever 11 and the tool holder 1 during assembly. In other embodiments, the tool holder 1 and the operating lever 11 can also be two independent components, which can be connected and fixed by means of screwing, snap-fitting, or other methods.

[0040] As shown in Figures 1 and 2, manual operation may be somewhat strenuous if the operating lever 11 is held directly for rotation. To facilitate operation, a radial force-applying lever 5 is detachably installed on the operating lever 11. When the user operates manually, by holding the radial force-applying lever 5 and pushing it to rotate, the tool holder 1 can be easily rotated, thereby achieving the purpose of chamfering the end face of the workpiece.

[0041] In this embodiment, the operating lever 11 is provided with a radial mounting hole 16. When manual operation is required, the radial force-applying rod 5 is passed through the radial mounting hole 16, so that both ends of the radial force-applying rod 5 protrude from the radial mounting hole 16. In this way, the operator can push the tool holder 1 to rotate by holding both ends of the radial force-applying rod 5. In order to facilitate the removal of the radial force-applying rod 5, the diameter of the radial force-applying rod 5 is slightly smaller than the inner diameter of the radial mounting hole 16, so that the radial force-applying rod 5 is in a movable fit with the radial mounting hole 16 after passing through it. This allows the radial force-applying rod 5 to be removed after use, making it easy to store and also facilitating the installation of the operating lever 11 into automated equipment for automatic processing.
